His leaving is generating a lot of speculation. Its be said before on other events but this may be the beginning of the end of NWN2.

One of the reasons I think is because I've never seen company forum guy as good as Rob before and I'm not even a big fan of the sequel. Bioware's approach was a lot more scattershot with devs coming in when they felt like it (which was still nice to see) and many other company liaisons aren't necessarily fans of the game they are liaisoning on. Rob actually explained why things happened the way they did at OE and though some of his answers were necessarily political I think he made an honest attempt to bridge the divide between dev and fan IMO.

Rob McGinnis
Brandon Adler and Matt Singh will be taking over the coordination and building of the patches. Matt Rorie will be handling the forums.

much of the speculation (and that's all it is at this point) is that Rob has jumped ship to Atari's developer for NWNOnline.

I come by now and then and intend to post where I can. I'll be up front and admit that I don't have Rob's technical knowledge of NWN2, though, so my role will likely be more limited than his was, at least on the forums.
